background and objectives: pseudomonas aeruginosa is an opportunistic pathogen that can produce biofilm. biofilm is a complex, three dimensional structure in which microorganisms are attached to a surface and embedded in a matrix made of extracellular polymers. due to high resistance to antimicrobial agents, biofilms create difficulties in various situations in healthcare. in this study, antibi...

as frequent in those with bactericidal activity (54%) as in those without (56%). The coexistence of bactericidal activity and bacteremia was reproduced and studied in experimentally infected weanling rats. Serum from such rats kills in vitro 95% of conventionally broth-grown bacteria within 10 min, but does not kill organisms obtained from the infected animals. Thus bactericidal activity as con...

in this study bactericidal activity of a malodor neutralizer containing silver nanoparticles manufactured in iran has been tested. for this purpose different concentrations of the product encounter with staphylococcus aureus, pseudomonas aeruginosa and bacillus cereus then the activity were evaluated in different contact times. the products containing at least 200 ppm of silver nanoparticles we...

BACKGROUND In this investigation, the urine samples obtained in a single oral-dose pharmacokinetic study were examined for their bactericidal activity against a range of relevant urinary tract pathogens. METHODS Six healthy volunteers received a single oral dose of ten oral antibiotics available in Croatia. Urine samples were taken every 2 h during the whole dosing interval of the particular ...

Bactericidal antibody is required for direct complement-mediated killing of most pathogenic gram-negative bacteria. Although it has been implicitly assumed that bactericidal antibody functions by increasing complement activation and deposition on the bacterial surface, this assumption may not be valid. We have shown previously (1) that bactericidal IgG increases the bactericidal efficiency of C...

silver nanoparticles have proved to possess significant antibacterial properties. nanosilver produced by electrochemical reduction stabilized by cellulose derivatives, has been evaluated by european standards (cen tc 216) in order to find out whether they could be applied in food, industrial, domestic and institutional areas as a suitable disinfectant. moreover, bactericidal activity of nanosil...

conclusions: with respect to the obtained results and regarding to the daily increase of the resistant microbial strains to the commercial antibiotics, it can be concluded that these extracts can be proper candidates of antibacterial substance against pathogenic bacterial species especially s. aureus, e. coli, k. pneumoniae and s. epidermidis. results: the extract of c. fistula was effective ag...
